A little more than a year ago, a very successful professional investor declared, “If you don’t own a home, buy one. If you own one home, buy another one, and if you own two homes, buy a third and lend your relatives the money to buy a home.”

Since that declaration, house prices have continued drifting lower in most parts of the country. The Case-Shiller index of national home prices is down about 4% year over year. Even so, we’re betting this professional investor was merely early…not wrong. US housing isn’t just cheap; it is the cheapest it has been in more than 40 years. And when one considers the possibility that inflation may rear its head soon, housing looks even cheaper still.
